meters, it being more particularly for me-.

tering water systems, and being especially of that type of meter employing a disk and known as a disk meter.

The object of the invention is to provide means for protecting the gearing which pchamber there is a bearing erates the registering device from the deteriorati'ng action of the water by preventing the access of the water thereto.

11 the accompanying drawings Figure 1 is a top plan view of the meter with the protecting cover broken away.

Fig. 2 is a longitudinal section.

Referring to the drawings, 1 represents the main barrel or chamber through which the water or other fluid flows, 2 representing the inlet and 3 the outlet. Iii this main cated therein by the webs'6, the webs being preferably formed in pairs and fitted together for the purpose of ready assembling or removal. I w

Mounted in the bearing 4 is a ball 7 which has connected therewith a and disk being formed preferablyof hard rubber. Also carried by-the, ball is a spindle 9. The construction so far described is one which is in common use in meters of this character and the action of the water as it passes through the casing 1 is such as to impart to the spindle 9 a nutatory movement.

- Clamped to the main casing 1 is a wall 10 having a centrally arranged beveled boss 11 which acts as a guide for the spindle -9 in its nutatory movement. The boss '11 is chambered or hollowed out to receive packing 12 and a nut 13 to form a packing box. Journaled in the boss 11 and nut 13 is a shaft 14 having a right-angled extension 15 arranged in the path of movement of the spindle 9 so that as the spindle nutates the shaft 14 will be revolved. This construc- 4, centrally lo-' disk 8, the ball tion, with the'exception of the division wall 10, is also old in meters of this character.

Connected to the shaft 14 is a worm 16 which meshes with the worm wheel 17 mounted in a bracket 18 on the upper side of the division wall 10. Eccentrically pivoted to the worm wheel 17 is a pawl lever mounted in a bracket 21 secured to the upper side of the division wall 10. This ratchet wheel 20 is operatively associated with a registering mechanism 22 of a well known form.

By the construction described it will be seen that the gearing which operates the registering mechanism is se arated from the water chamber 1 by the division wall 10 and by reason of the packing box described it is impossible for the water which passes throughthe chamber with this gearing so that deterioration of the gearing by the action of the water thereon is prevented. The registering mechanism and gearing are preferably inclosed by a cap 23, the cap 23, the division wall 10 and the main casing 1 being all connected together in any suitable Way which will permit their ready separation.

Having thus described my invention, I claim 1. In a meter, a main open top chamber, a fluid chamber therein'insertible through the open top thereof, a fluid operated member in said fluid chamber, a fluid tight cover for the top of said main chamber, register- 1 to come in contact 19 which cooperates with a ratchet wheel 20 ing mechanism and operating devices there- 7 I for located on the top of said cover, an operativeconnection from said fluid operated member to said operating devices extending through a in position, a registering mechanism and its operating devices located directly on the top of said cover, a casing for said registering mechanism and operating devices, and an operative connection from said fluid operated, member to said operating devices extending through a fluid tight bearing in said fluid tight cover, and means common to the main chamber, cover and casing for clamping all three parts to ether.

In testimony whereof, I ave hereunto set my hand this 29th day of October, 1918.
